Hiki ke hoʻomaopopo i ka welding friction stir welding i waena o nā mea like ʻole, e like me nā metala, ceramics, plastics, etc. hana kiʻekiʻe.
4. Kuʻi uila uila
Electron beam welding is a weld method that hoʻohana i ka wela wela i hana ʻia e ka electron beam wikiwiki a hoʻopaʻa ʻia i ka weldment i hoʻokomo ʻia i loko o kahi ʻūhā ʻole a i ʻole.
Electron beam welding ua hoʻohana nui ʻia i nā ʻoihana he nui e like me ka aerospace, atomic ikehu, ka pale aupuni a me ka ʻoihana koa, nā kaʻa, a me nā mea uila a me nā mea uila ma muli o kāna mau pono o ka pono ʻole o nā koʻokoʻo welding, ʻaʻole maʻalahi e oxidize, maikaʻi ka hana hou ʻana, a liʻiliʻi thermal deformation.
ʻO ka loina hana o ka welding beam electron
Paʻa nā electron mai ka emitter (cathode) i ka pū electron. Ma lalo o ka hana o ka uila uila, ua hoʻonui ʻia nā electrons i 0.3 a 0.7 mau manawa o ka māmā o ka māmā, a loaʻa kekahi ikehu kinetic. A laila, ma o ka hana a ka lens electrostatic a me ka lens electromagnetic i loko o ka pū electron, ua hoʻohuli ʻia lākou i kahi kukuna electron me kahi kiʻekiʻe kiʻekiʻe.
Paʻi kēia kukuna electron i ka ʻili o ka mea hana, a ua hoʻololi ʻia ka ikehu kinetic electron i ikehu wela, e hoʻoheheʻe a hoʻoheheʻe koke ʻia ka metala. Ma lalo o ka hana a ka mahu metala kiʻekiʻe, ua "wili" koke ʻia kahi puka liʻiliʻi ma luna o ka ʻili o ka mea hana, ʻike ʻia hoʻi he "keyhole". I ka neʻe ʻana o ke kukuna electron a me ka mea hana e pili ana i kekahi i kekahi, kahe ka metala wai a puni ka lua liʻiliʻi i ke kua o ka loko i hoʻoheheʻe ʻia, a maloʻo a paʻa e hana i kahi weld.

ʻO nā hiʻohiʻona nui o ka welding beam electron
Hiki i ka Electron beam ke komo ikaika, kiʻekiʻe kiʻekiʻe o ka mana, nui weld hohonu-a-ākea ratio, a hiki i 50: 1, hiki ke hoʻomaopopo i ka hana ʻana o nā mea mānoanoa hoʻokahi, a hiki i ka 300mm ka mānoanoa welding.
Hiki i ka wiliwili maikaʻi, ka wikiwiki wiliwili wikiwiki, ʻoi aku ma mua o 1m/min, wahi liʻiliʻi i hoʻopili ʻia i ka wela, liʻiliʻi wiliwili deformation, a me ke kiʻekiʻe o ka hoʻolālā kuʻihao.
Hiki ke hoʻololi ʻia ka ikehu uila uila, hiki ke hoʻololi ʻia ka mānoanoa o ka metala welded mai ka lahilahi e like me 0.05mm a i ka mānoanoa e like me 300mm, me ka ʻole o ka beveling, hoʻokahi manawa hoʻoheheʻe ʻia, ʻaʻole hiki ke loaʻa i nā ʻano hana kuʻi.
ʻO ka laulā o nā mea i hiki ke welded e ka electron beam he mea nui, kūpono loa no ka wili ʻana i nā metala ikaika, nā metala refractory a me nā mea hana me nā koi kiʻekiʻe.
5. Ultrasonic metala wiliwili
ʻO ka hoʻoheheʻe ʻana i ka metala kani he ala kūikawā ia o ka hoʻopili ʻana i nā metala like ʻole a i ʻole me ka hoʻohana ʻana i ka ikehu haʻalulu mechanical o ke alapine kani ultrasonic.
Ke hoʻopili ʻia me ka ultrasonically, ʻaʻole hoʻohana ʻia ke kumu wela o kēia manawa a i ʻole ka wela wela i ka mea hana. Hoʻololi wale ia i ka ikehu vibration o ke kiʻi i ka hana friction, ka ikehu deformation a me ka piʻi ʻana o ka mahana i ka mea hana ma lalo o ke kaomi static. ʻO ka hoʻopaʻa ʻana i ka metallurgical ma waena o nā ami ʻo ia kahi kuʻi paʻa paʻa i loaʻa me ka hoʻoheheʻe ʻole ʻana i ka mea makua.
Hoʻopau maikaʻi ʻo ia i ka spatter a me ka oxidation phenomena i hana ʻia i ka wā kuʻi kūʻē. Hiki i ka welder metala kani ultrasonic ke hana i ka hoʻoheheʻe ʻana i hoʻokahi kikoʻī, ka hoʻoheheʻe multi-point a me ka wili pōkole ma luna o nā uwea lahilahi a i ʻole nā ʻāpana lahilahi o nā metala non-ferrous e like me ke keleawe, ke kālā, ka aluminika a me ka nickel. Hiki ke hoʻohana nui ʻia i ke kuʻi ʻana o nā alakaʻi thyristor, nā fuse sheet, nā alakaʻi uila, nā ʻāpana pole lithium a me nā pepeiao pole.
Hoʻohana ʻo Ultrasonic metala i nā hawewe haʻalulu kiʻekiʻe e hoʻouna i ka ʻili metala e welded. Ma lalo o ke kaomi, ʻāwili nā ʻili metala ʻelua i kekahi i kekahi e hana i ka hui ʻana ma waena o nā papa molekala.
ʻO nā pōmaikaʻi o ka welding ultrasonic metala he wikiwiki, mālama i ka ikehu, ikaika fusion kiʻekiʻe, conductivity maikaʻi ʻole, ʻaʻohe ʻula, a kokoke i ka hana anu; ʻO nā hemahema, ʻaʻole hiki ke mānoanoa loa nā ʻāpana metala i hoʻopaʻa ʻia (ʻoi aku ka liʻiliʻi a i ʻole like me 5mm), ʻaʻole hiki ke kiʻekiʻe loa ka helu kuʻi, a koi ʻia ke kaomi.
6. Ka wiliwili ʻana i ke kī
ʻO ke kumumanaʻo o ka welding butt flash ʻo ia ka hoʻohana ʻana i kahi mīkini kuʻi kuʻi e hana i ka metala ma nā ʻaoʻao ʻelua e pili ana, e hele i kahi kaha haʻahaʻa haʻahaʻa haʻahaʻa, a ma hope o ka wela ʻana o ka metala i kahi mahana a palupalu, hana ʻia ke kaomi axial e hana ai. he ami wili pu.
Ma mua o ka hoʻopili ʻana o nā welds ʻelua, ua hoʻopaʻa ʻia lākou e nā electrodes clamp ʻelua a pili i ka lako mana. Hoʻoneʻe ʻia ke koʻi hoʻoneʻe ʻia, a ʻo nā maka hope o nā welds ʻelua e hoʻopili māmā ʻia a hoʻohana ʻia no ka hoʻomehana ʻana. Hoʻokumu ka wahi hoʻopili i ka metala wai ma muli o ka hoʻomehana ʻana a me ka pahū ʻana, a ua hoʻopuʻi ʻia nā huna huna e hana i nā uila. Ke hoʻoneʻe mau ʻia ka puʻupuʻu hoʻoneʻe, a mau ka uila. Pumehana nā welau ʻelua o ka weld. Ma hope o ka hōʻea ʻana i kahi mahana, ʻoki ʻia nā maka hope o nā mea hana ʻelua, ʻoki ʻia ka mana welding, a hoʻopaʻa paʻa ʻia lākou.
Hoʻopili ʻia ka wahi hoʻopili ma ka hoʻomehana ʻana i ka hui weld me ke kūpaʻa, hoʻoheheʻe i ka metala maka hope o ka weld, a hoʻohana koke ʻia ka ikaika kiʻekiʻe e hoʻopau i ka wili.
ʻO ka rebar flash butt welding he ʻano kuʻi puʻupuʻu e kau ai i ʻelua mau pahu i loko o kahi ʻano hui pū, hoʻohana i ka wela kūpaʻa i hana ʻia e ke au kuʻi e hele ana ma ka wahi hoʻopili o nā rebar ʻelua e hoʻoheheʻe i ka metala ma kahi kikoʻī, hoʻopuka i ka spter ikaika. , ʻālohilohi, hele pū ʻia me kahi ʻala ʻala, hoʻokuʻu i nā molekala ʻimi, a hoʻohana koke i ka ikaika forging top e hoʻopau i ke kaʻina hana.
